kernel 20261106-ac41e133 arm64

EmiBSD kernel for arm64, built by just dist-arm64 from commit ac41e133 (main, milestone N5 under way; N5.8 isofs done). It replaces 20261106-ea7fc032.

What changed from 20261106-ea7fc032

• The kernels are built without the qemu feature. In ea7fc03, halt ended in QEMU's semihosting exit, which traps ("Unknown kernel exception 0x00") on a machine started without -semihosting-config. Now halt waits for a key, as OpenBSD's does.
• BUILDINFO no longer holds a clock time, so one commit packs the same tarball that day. Two packs of this commit gave the same sum.
• The kernel now includes N5.8: cd9660 and udf are the native kernel's.

One tarball for EmiBSD/OS to assemble the install media with Userland's sets. Fetch it by this tag, check the sum, then unpack:

Inside kernel-20261106-ac41e133-arm64/, covered by its SHA256 (OpenBSD's format):

File	What
bsd.mp	the MULTIPROCESSOR kernel, release profile (LTO, symbols kept), default features (no qemu)
bsd.RAMDISK	the same kernel with an empty 32 MiB ramdisk (65536 sectors); cargo xtask rdsetroot fills it with a miniroot to make bsd.rd
abi_openbsd.ko	the OpenBSD ABI module the boot loader hands the kernel (required)
BOOTAA64.EFI	the EFI boot loader
BUILDINFO	commit, dates, toolchain (rustc 1.99.1), LandingZone pin, profiles

Pre-release: a development build, tested only under QEMU (virt). Before packing, this very kernel boots once: the user-mode checks of smoke-boot up to init's last one, then OpenBSD's "init died" panic. arm64 only until amd64 is homologated (N10). Known open issue: the installer formats the MSDOS partition through a zero DUID (/dev/r0000000000000000.i). It is being investigated.
